People
Brandon Chalifoux, Assistant Professor

Prior to joining the College of Optical Sciences (2020-present), I completed my Ph.D. and Postdoctoral training at MIT in the Space Nanotechnology Laboratory. I completed a B.S. in Mechanical Engineering at Rice Unviersity. Aside from research and teaching, I enjoy rock climbing, mountain biking, and trying to avoid the cholla during both.
Graduate students
Kevin Laverty, PhD student (Optical Sciences)

I began my PhD at the College of Optical Sciences in 2020.
Brody McElwain, PhD student (Optical Sciences)

I graduated from Penn State with a B.S. and M.S. in Engineering Science and Mechanics in 2022. I started my PhD in Optical Sciences at UofA in 2022. My research involves using USP and Bessel beam optics to fabricate spacers used to align x-ray mirrors. In my spare time I enjoy climbing, live music, and going to the movies.

Research staff
Ian Arnold, Research Engineer

I have been a Research Engineer at the University of Arizona since 2018. Prior to that I completed a M.S degree in Optical Sciences at the University of Arizona working with ultrafast attosecond spectroscopy. I also received a M.S. and B.S. degrees in physics from the University of Nevada, Reno where I built atmospheric instrumentation. I am a very hands-on person who enjoys building things.
